What was the last thing you did for play or fun?

What is the river hiding?
What secret does the
Water hold deep or in
The shallows under the
Cover of rippling eddies?
Or gentle waves in the
Shallows though we
Know it runs deeper
Hiding its mysteries in
The shallow waters or
In the middle where it
Deepens as the river
Bed drops, its floor a
Concave of complex
Vegetation and mud
